    Modeling Transient Discharge into a Tunnel Drilled in a Heterogeneous Formation

    Perrochet, Pierre ; Dematteis, Antonio

    In: Ground Water, 2007, vol. 45, no. 6, p. 786-790

    An analytical model is developed to predict transient discharge flow into a tunnel drilled at various speeds through a heterogeneous formation. This model relies on simplifying assumptions commonly enforced in hydrogeologic engineering, and combines the convolution and superposition principles to account for composite sections with arbitrary parametric contrasts. An application to the data...
